Please help with my question it is the millers shower uses 25 gallons of water for a 10 min shower. Now how many gallons of wate
klasskru [66]
Answer: The Millers need 15 gallons of water for 6 minutes.


Lets start by finding how much water is needed for 1 min shower. 
<span>
25 gallons of water is used for 10 min shower:

</span>10 mins = 25 gallons <span>

To find 1 min shower, we will divide the 25 gallons of water by 10. 
</span><span>
10 mins = 25 gallons            </span>← Divide by 10 on both sides<span>
÷ 10           ÷ 10
1 min = 2.5 gallons

Now that we know the Millers need 2.5 gallons for every 1 minute of shower, we can find 6 minutes of shower by multiplying by 6.

1 min = 2.5 gallons</span>         ← Multiply 6 on both sides<span>
   x6           x6
6 min = 15 gallons

-----------------------------------------------</span>---------------------------------------<span>
Answer: The Millers need 15 gallons of water for 6 minutes.

HELP FAST!!! The Mogul Runners ski club planned a trip to Park City. Of the total number of club members, 11 signed up to go. If
Andre45 [30]

"25%" means "0.25"
"of" means "times"

You said                                                  11 members =  0.25 x (the club)

Divide each side by  0.25 :      The club = (11 / 0.25)  =<em>  44 members

</em>
This is as fast as I can type.<em>

Triangle RST is rotated 90° in a clockwise direction. What is the name of the image after the rotation?
Art [367]
When the triangle RST is rotated by <span>90° in a clockwise direction, the name of the image after the rotation would be SRT.

The reason you get a name like this is because you're not only rotating the triangle, you also rotating the letters along with the image.

I need help with the top 3 plz
attashe74 [19]

Answer/Step-by-step explanation:

Recall: SOHCAHTOA

1. Reference angle = 70°

Adjacent side = x

Hypotenuse = 6 cm

Apply CAH. Thus,

Cos 70 = adj/hyp

Cos 70 = x/6

6 × cos 70 = x

2.05 = x

x = 2.05 cm

2. Reference angle = 45°

Adjacent side = x

Hypotenuse = 1.3 m

Applying CAH, we would have the following ratio:

Cos 45 = adj/hyp

Cos 45 = x/1.3

1.3 × cos 45 = x

0.92 = x

x = 0.92 m

3. The who diagram is not shown well. Some parts are missing, however you can still solve the problem just the same way we solved problem 1 and 2.
